Dell OS10 (10.5.3.0 in GNS3) unable to make portchannel active when in a VLT

Hello theFreeze,

Have you tried using the GNS3 bundle?

Here is the link to download the OS10 virtualization bundle

Hi Charles,

we downloaded the image yesterday:

switch-b# show version
Dell SmartFabric OS10 Enterprise
Copyright (c) 1999-2023 by Dell Inc. All Rights Reserved.
OS Version: 10.5.5.5
Build Version: 10.5.5.5.105
Build Time: 2023-06-19T19:08:01+0000
System Type: S5224F-VM
Architecture: x86_64
Up Time: 00:04:05

But the result is similar. Also the first time I enabled logging mon it worked, but after a reboot it fails.
We want to buy some Dell switches but testing if that will ever work how we intend to use it is nearly impossible like this.

I noticed that during boot it says:

Loading OS10 ...
[ 1.146464] kvm: no hardware support
[ 8.697898] intel_rapl: driver does not support CPU family 6 model 6

Debian GNU/Linux 10 switch-b ttyS0

Dell SmartFabric OS10 Enterprise

Apararently it doesn't like the CPU? 
We have GNS3 running in hyper-v as a VM with 38 cores and 64GB internal memory, so it certainly shouldn't be lacking resources

Hi @theFreeze,

Try the image version 10.5.4.7.

Hi Joey,

you saw that I tried 10.5.3 and 10.5.5. Can you give a hint why 10.5.4. should work instead 10.5.3. and 10.5.5 ?

Hello theFreeze,

I think it was just an oversite by Joey.

Hi Charles,

as pointed out in the question: the setup DOES work on physical switches, it DOES NOT work when using the Dell supplied virtual switch image on GNS3 (tried versions 10.5.3.0 and 10.5.5.5). So the issue is not the configuration setup in OS10, it is that somehow VLT does not want to work in GNS3.

I do have similar issues when I try a similar setup using Cisco equipment and their dialect VPC, which makes me wonder if this is a hard limitation of the usage of GNS3 -or- that some special settings need to made in GNS in order to make this work.

Is there any other reader of this forum that has ever seen a setup with VLT -AND a portchannel to a third device working IN GNS3? So that I at least know that it can work?

Kindest regards,
theFreeze

Hello theFreeze,

I see, since it is doing it with Cisco and OS10 it may be a fault of GNS3.

I haven't found anything more yet.

Hopefully anyone in the community that has used GNS3 can add their experience.
